We show that the rainbow state, which has volume law entanglement entropy for most choices of bipartitions, can be embedded in a many-body localized spectrum. For a broad range of disorder strengths in the resulting model, we numerically find a narrow window of highly entangled states in the spectrum, embedded in a sea of area law entangled states. The construction hence embeds mobility edges in many-body localized systems. This can be thought of as the complement to many-body scars, an `inverted quantum many-body scar', providing a further type of setting where the eigenstate thermalization hypothesis is violated., Comment: 6 pages, 4 figures, v2: accepted version
